There exists a vulnerability in exception sanitization of vm2 for versions up to 3.9.16, allowing attackers to raise an unsanitized host exception inside `handleException()` which can be used to escape the sandbox and run arbitrary code in host context. This vulnerability was patched in the release of version `3.9.17` of `vm2`. There are no known workarounds for this vulnerability. Users are advised to upgrade.","published_at":"2023-04-17T21:42:10.514000Z","last_modified_at":null,"cvss_v3_score":9.8,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","cvss_v3_severity":"CRITICAL","cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":"poc","ssvc_automatable":true,"ssvc_technical_impact":"total","cwes":["CWE-74"],"nvd_references":["https://github.com/patriksimek/vm2/security/advisories/GHSA-ch3r-j5x3-6q2m","https://github.com/patriksimek/vm2/commit/4b22e87b102d97d45d112a0931dba1aef7eea049","https://github.com/patriksimek/vm2/commit/f3db4dee4d76b19869df05ba7880d638a880edd5","https://gist.github.com/leesh3288/381b230b04936dd4d74aaf90cc8bb244"],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-24T00:09:39.878444Z","updated_at":"2026-06-29T01:30:03.723887Z"},"effective_severity":"CRITICAL","badges":["epss"],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack Vector","value":"N","value_label":"Network"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"PR","name":"Privileges Required","value":"N","value_label":"None"},{"metric":"UI","name":"User Interaction","value":"N","value_label":"None"},{"metric":"S","name":"Scope","value":"U","value_label":"Unchanged"},{"metric":"C","name":"Confidentiality","value":"H","value_label":"High"},{"metric":"I","name":"Integrity","value":"H","value_label":"High"},{"metric":"A","name":"Availability","value":"H","value_label":"High"}]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"patriksimek","vendor_name":"patriksimek","product_slug":"vm2","product_name":"vm2","version_start":"< 3.9.17","version_start_inclusive":true,"version_end":"< 3.9.17","version_end_inclusive":true,"cpe23_uri":"cve5:patriksimek:vm2:< 3.9.17:< 3.9.17"}],"exploit_refs":[],"news":[],"references":[{"url":"https://github.com/patriksimek/vm2/security/advisories/GHSA-ch3r-j5x3-6q2m","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://github.com/patriksimek/vm2/commit/4b22e87b102d97d45d112a0931dba1aef7eea049","source_type":"PATCH","tags":["patch"]},{"url":"https://github.com/patriksimek/vm2/commit/f3db4dee4d76b19869df05ba7880d638a880edd5","source_type":"PATCH","tags":["patch"]},{"url":"https://gist.github.com/leesh3288/381b230b04936dd4d74aaf90cc8bb244","source_type":"MISC","tags":[]}],"timeline":[{"type":"published","at":"2023-04-17T21:42:10.514000Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:28:06.953192Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:28:06.953192Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:28:06.953192Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"ssvc_changed","at":"2026-06-29T01:30:03.723887Z","label":"SSVC decision revised","source":"vulnrichment"},{"type":"ssvc_changed","at":"2026-06-29T01:30:03.723887Z","label":"SSVC decision revised","source":"vulnrichment"},{"type":"ssvc_changed","at":"2026-06-29T01:30:03.723887Z","label":"SSVC decision revised","source":"vulnrichment"}]}
